Killed: Shaaliver Douse, 14, was killed by police early Sunday. Officers say he pointed a gun at them

The gun found on the body of a 14-year-old boy shot dead by NYPD cops earlier this month was originally purchased at a Kentucky gun show the same year the slain teen was born.

Federal investigators, hoping to learn how the 9mm Astra semi-automatic pistol got into the hands of young Shaaliver Douse, have tracked the gun back to Brian Quigley, of Crestview, Kentucky.

Quigley bought the gun from T&J Sporting Goods in 1997 - the very same year that Shaaliver was born in the Bronx, New York.

Quigley told the New York Daily News he gave the Spanish-made pistol to his roommate as partial payment for rent he owed.

'That gun was a piece of s***,' he said.

When told that the gun had made it all the way to New York and was used by a teenager, Quigley was shocked.

'That’s crazy. I can’t believe that gun made it all the way out there,' he said.

Quigley said he 'thought' his roommate handled the transfer paperwork on the pistol - though federal investigators found that the last recorded transaction for the gun was in 1997 when Quigley purchased it legally.

Quigley's former roommate reportedly told investigators that the gun was stolen, though he never filed a theft report on the weapon.

Quigley, however, said the roommate sister was involved with people in gangs in New York and Florida. Scroll down for video

The NYPD says a rookie white police office shot and killed Shaaliver August 4 after the teenager raised the pistol and fired when two officers commanded him to stop and drop the weapon.

Police released a gory picture of the black gun covered in the boy's blood.

The New York City Police Commissioner, Ray Kelly, concedes that the teen may be the youngest person ever killed by the NYPD.

The crime scene (pictured here) was located in the Bronx where in the early hours of the morning two uniformed police officers found boy firing at a fleeing man

Ms Barcene likened the shooting to
the death of Trayvon Martin in Sanford, Florida - a case that sparked
outrage across the country.

'Him,
Trayvon Martin, it’s never going to end.' she said. 'A child. Fourteen
years old. Fourteen years old. Gone. Shot in the head. By police.'

Many
in the black community remain highly skeptical of the NYPD over the
shooting death in march of 16-year-old Kimani Gray in Brooklyn. Police
said the teen also had a gun, though the shooting drew marches across
the borough in protest of the killing.

Sunday
was not Shaaliver's first run-in with police. In May, he was arrested
and charged with attempted murder after he shot and wounded a
15-year-old boy in the neighborhood. Police say they used surveillance
video from that that incident to identify Shaaliver among a group of
teens running from the scene.

However, those charges were later
deferred and Shaaliver was released back onto the streets when the
15-year-old victim couldn't testify against his shooter. Police believe that shooting was gang-related, as well.

The fatal shooting occurred in the Bronx at the volatile corner of Courtlandt Avenue & 151st Street

The shooting occurred right near this Bronx convenience store where police discovered Douse firing shots at a fleeing man

Police
said the altercation Sunday started when Shaaliver, who lives in a
nearby housing project with his mother, opened fire on a man standing
outside a bodega in the crime-ridden Melrose section of the Bronx.

The target fled, running down the street, with Shaaliver chasing after him.

Two
officers, age 26 and 27, who had jointed the NYPD in January and
graduated from the academy last month, were in the area as part of an
Operation Impact deployment of police in the neighborhood.

The
uniformed officers identified themselves as police and ordered
Shaaliver to drop his weapon when they confronted him, authorities said.

Instead of dropping the weapon, police say, he raised it and pointed at the officers.

One
of the officers opened fire shot him in the left side of the jaw,
police said. The teenager was pronounced dead at the scene.

'(The officers) literally were half a block away from where the (first) shots were being
fired,' a police source told The New York Daily News. 'They ran
to the corner and there it was.'

The man Shaaliver was firing at is still at large.
